Instructions:

In a large bowl, whisk together olive oil, red wine vinegar, and pepper. Add tuna, carrot, red onion, broccoli, and celery and toss to combine.

Lay out lettuce leaves and distribute tuna mix evenly on each of the lettuce leaves.

Serve the wraps.
For lunchboxes, pack the tuna separately from the lettuce and assemble the wraps when you are ready to eat. Or pre-make the wraps and tightly wrap each in a piece of plastic wrap or aluminum foil to keep it secure.
